Computed volumetric and gravimetric energy densities [in the 116-hour experiment] were found to be far above those of any
known chemical source. Even by the most conservative assumptions as to the errors in the
measurements, the result is still one order of magnitude greater than conventional energy sources.

The results obtained indicate that energy was produced in decidedly higher quantities than what may be gained from any conventional source.
That, plus refusing to unplug the device while it was in operation or have the power pass directly through a measuring device rather than using magnetic effects to measure it, pushes it into obvious hoax territory.
Has Rossi done it? Will he be Emperor after all?

More articles, pro, contra.
The older article at http://scienceblogs.com/startswithabang/2011/12/05/the-nuclear-physics-of-why-we/ basically demolishes any possibility that it is anything but a hoax. There is literally no way that the reaction can be producing the observed (normal Earth crust) ratio of copper isotopes, even if you ignore the complete lack of radiation.
